What is 319/1000 as a decimal?

• A. 0.0319
• B. 0.319
• C. 0.00319
• D. 3.19

Answer: (B)

When a fraction has a denominator that is a power of 10, converting it to a decimal is just placing the decimal point so that you’ve divided by that power of 10. Here, 1000 is 10^3, so dividing by 1000 moves the decimal three places to the left. The numerator 319 becomes 0.319. That’s why the decimal form is 0.319. The other options would require shifting the decimal a different number of places (four, five, or placing it in a way that corresponds to a denominator like 100), so they don’t match 319/1000.
